$\sf{C.P = {\huge{[}}\frac{100}{100 \: + \: Gain \: \%} \huge ] } \: \times S.P$

$\sf{C.P = {\huge{[}}\frac{100}{100 \: + \: 6.5 \: \%} \huge ] } \times 8900 \\ \\ \implies \sf{Rs. \: 57851}$

Here is your answer.
SP = 8900
Profit% = 6.5%

As we know the formula
CP = SP × 100/(100 + Profit%)
$= \frac{8900 \times 100}{(100 + 6.5)} \\ \\ = \frac{890000}{106.5} \\ \\ = 8356.80$
Therefore Cost price is Rs 8356.80
